As we announced in early November, the new Google Drive will soon become the default experience for all users. Though users have had the ability to revert to the old Drive UI through the Settings drop down, this will change in the U-M domain in the next week or so. Drive is being updated across all platforms, so users will notice changes everywhere they access Drive.
For more information, see Meet the new Google Drive. Be sure to check out the Meet the new Google Drive video, which we've also posted on google.umich.edu.
